While working with the Treeview, I noticed that checkboxes would only work if I switched from 2012.2.xxxx to 2012.3.xxxx. Fine. After switching to the 3Q release, I get bad behavior with the Grid. Without changing the code, only switching the reference from 2Q to 3Q CSS & JS, the checked-treeview now works but the Grid does not. Am I missing something?
